title: Vacuum-assisted vaginal delivery.
abstract: The second stage of labor is a dynamic event that may require assistance when maternal efforts fail to effect delivery or when there are nonreassuring fetal heart tones. Therefore, knowing how to perform an operative vaginal delivery with forceps or vacuum is vital for family physicians who provide maternity care. Vacuum is rapidly replacing forceps as the predominant instrument, but each has advantages and disadvantages, including increased risk of maternal trauma with forceps and increased risk of neonatal cephalohematoma with vacuum. Use of a second instrument if the first one fails is associated with worse outcomes. Routine episiotomy in operative vaginal delivery is no longer recommended. The "ABCDEFGHIJ" mnemonic can facilitate proper use and application of the vacuum device and minimize risks, and practicing the techniques on mannequins can provide an introduction to the skills of operative vaginal delivery.
